Answer: 
Step-by-step explanation:
The perpendicular slope of the line(m) =
:
- m = -4 ⇒

The function formula is y = mx + b, where the y-intercept(b) is found by substituting in the values of a point on the line ⇒ (4, -6):

<u>So the perpendicular equation is </u>
<u>.</u>
Looking at the image of the cube you can see the outer edges would have paint on 2 sides and the corners would have paint on n3 sides.
The only ones with paint on one pace is the center cubes.
There are 6 sides to a cube and there would be 6 center pieces.
Answer: 6
The slope is the change in Y over the change in X
Slope = (-5 - -10) / (-2 - -9) = (-5+10) / (-2+9)
Slope = 5 / 7

Answer:
(a) 1 and 3; 2 and 4
Step-by-step explanation:
In this figure, adjacent angles are linear pairs, so are supplementary. The only angles that are not are the vertical angles.
1 & 3, 2 & 4 are not supplementary
